Microcontroller › 8051 › Question about component??
Hi every buddy
I wanna ask about this component ?? what is it ?? is it a resistor with three pins?? or what? See the pic
And the Crystal how much Hz??
thanks
Dear,
Highlighted componant is variable resistor.
It is a variable resistor, with the middle pin can be slided in both directions to vary the resistance value across the middle pin and any of the other pin.
OK .. but how much will be??? 25k ??
Normally we use 10K
dont confuse with those resistors.. that resistor for controling the contrast of lcd.. if u connected high resistance value contarast will be less and vice versa
